NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 644,307, dated February 27, 1900.

Application filed $eptember 15, 1899. Serial No. 730,571. (No model.)

To (all whom it may concern:

Be it known that we, EDWARD W ATKINS and CHARLES OOLTERYAHN, citizens of the United States of America, residing at Pitts burg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Nut-Locks, of which the followingisaspecification,referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in nut-looks, and more particularly to nut-locks employed for use on railway-rails and other structures where it is desired to look a series of nuts and bolts at the one time.

The invention has for one object to construct a nut-lock of the above-referred-to class that will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture.

The invention has forits still further object to construct a nut-lock that may be easily applied and removed when desired; furthermore, a device of this class that will be highly efficient in its operation and retain the nuts in their proper position at all times.

With the above and other objects in view the inven tion finally consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, and in which- Figure 1 is a side elevation of a section of a rail with our improved nut-lock applied thereto. Fig. 2 is a similar view of the modified form of the same. Fig. 3 is a vertical sectional View taken on the line 3 3 of Fig. 1. Fig. 4 is a similar view taken on the line 4: 4 of Fig. 2. Fig. 5 is aperspective view of the retaining-plate, partly broken away. Fig. 6 is a perspective view of the clamp employed in the modified form of our invention. Fig. 7 is a similar view of the clamp employed in the construction as shown in Fig. 1 of the drawings.

5 represents the clamp, and 6 indicates the retaining-plate, said clamp 5 in the modified form being provided centrally with a bolthole 5.

The reference-numeral 7 indicates rectangular openings cut in the retaining-plate 6.

The manner in which our improved nutlock is placed in position is as follows: The clamp 5 is placed in the rear of the fish-plate adjacent to the web of the rail. The fishplate is then applied, and after the nuts are all lined up in proper position the retainingplate is applied over the ends, engaging the sides thereof and holding the same in proper position. The ends of the clamps are then turned over downwardly and upwardly, serving to hold the retaining-plate in position. When it is desired to remove the nut-look, the ends of the clamps are turned upwardly, allowing the removal of the retaining-plate, and the nuts upon the ends of the bolts may then be readily removed.

In the modified form we have shown a bolthole through the clamp, allowing the bolt to pass through said clamp and operating in substantially the same manner.

The many advantages obtained by the use of our improved nut-lock will be readily understood from the foregoing description and a further explanation is deemed unnecessary.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The combination with a rail, of a pair of clamps adapted to be mounted against one side of the web of said rail and clamped between the underneath face of the top and the upper face of the base, a fish-plate secured to the said clamps, prevented thereby from engaging the web of the rail and provided with a series of circular openings, a retaining-plate secured in the said clamps and provided with a series of rectangular openings registering with the openings of the said fish-plate, a fishplate engaging the web of the'rail opposite the first-named fish-plate and provided with a series of circular openings, aseries of bolts engaging through the openings of the fish and retaining plates and through the web of the rail, said bolts having the heads thereof engage the last-named fish-plate and their screw-threaded ends extend through the rectangular openings of the retaining-plate, and a nut mounted 011 the screw-threaded end of I 5 each bolt and adapted to engage the walls of the rectangular openings to preventits turning when in position, substantially as set forth.

In testimony whereof we affix our signa- 2o tu res in the presence of two witnesses.
